NOTE
I've personally stopped using this image! These days I just use msmtp instead, which gives my application direct feedback on the success/failure instead of filling up a "frozen" queue in exim4 that I then also have to manage. At some point, I'll probably stop maintaining this image entirely.
Hopefully not gonna cause any issues in the future. But I'd prefer we move to this though https://hub.docker.com/r/ixdotai/smtp, since it also support arm64.
According to https://develop.sentry.dev/self-hosted/email/ sentry self hosted is using exim4
But exim4 is phaseout https://hub.docker.com/r/tianon/exim4
